MACHINE FOR ROLLING OR CRIMPING END SEAMS F SHEET-METAL CANS.

SPECIFICATION forming part of- Letters Patent No. 522,269, dated July 3, 1894.

Application filed July 23, 1892. Renewed March 14, 1894. Serial No. 503,554- (No model.)

To all whom it may concern:

Be it known that We, EDWIN NORTON and JOHN G. HODGSON, residing at Maywood, in the county of Cook and State of Illinois-and FRANK M. LEAVITT, residing at Brooklyn, in the county o'fiKings and State of New York, citizens of the United States, have invented a new and useful Improvement in Machines for Rolling or Crimping the End Seams of Sheet- Metal Cans, of which the followingis a specification.

Our invention relates to machines for rolling or crimping the seams of sheetmetal cans.

In the manufacture of sheet metal cans, and especially large polygonal cans, such for example as those used for petroleum, after the heads have been applied to the can bodies and the seams squeezed to a greater or less extent, it is desirable that the seams or flanges uniting the head and body should be firmly and securely rolled together to the end that the struction which will serve to perform this work automatically and properly.

To this end the machine We have invented comprises a pair of reciprocating dies adapted to fit within the countersunk flanges of the can head and support the same on the inside, rotatable seaming rollers operating in con- Junction therewith and mounted upon pivoted levers carried by a revolving'wheel or carrier, stationary cams for pressing such rollers against the seam as they are carried around the can by their revolving carrier, a revolving wheel or feed device having half molds or pockets to receive the can bodies from a delivery chute or conveyor and carry them around into position to register with said dies, and a reciprocating half mold: or pocket to aid in supporting the can and con tering it with the dies, and mechanism for automatically operating these parts. I

Our invention consists in the novel devices and novel-combinations of parts and devices herein shown and described and more particularly pointed out in the claims.

In the accompanying drawings which form a part of this specification and in which similar letters of reference indicate like parts throughout all the views, Figure 1 is a plan view of our machine. Fig. 2 is a rear elevation. Fig. 3 is an end elevation. Fig. 4 is a central vertical section taken on line 4=4 of Fig. 1. Fig. 5 is a vertical longitudinal section taken on the line 5-5 of Fig. 3. Fig. 6 is an enlarged detail section of the rollers and dies for rolling or crimping the seam. Fig. 7 is a detail elevation of one of the crimping dies and the rollers operating in conjunction therewith. Fig. 8 is a plan view partly in section of the reciprocating half mold or pocket in which the can body is su'pportedin part during the operation.

' In the drawings A represents the frame of the machine. e

B and O are the half molds or pockets between or'by which the can body is heldwhile being operated upon. The half molds or pockets B are several in number and formed in or mounted on an intermittently revolving wheel B or. other suitable or equivalent device for feeding or conveyingthe can bodies automatically into position in front of 'the movableor reciprocating half mold or pocket 0 and in position to register with the reciprocating dies D which fit in the countersink a: of the can heads X so as. to support the flanges 00' on the inside while being operated upon by the crimping, seaming or squeezing rollers-F on the outside. The reciprocating dies D are secured to or carriedby bars or shafts D connected with reciprocating slides orcross heads D which work back and forth in suitable guides D on the frame of the machine. Carried by this same cross head or the connecting bar D forming part thereof, are two stationary grooved camsE and E for operating the levers F F upon which the crimping rollers F are journaled. The levers F and F are bent levers and are pivoted at f to the revolving wheel or carrier G;

levers F and F are'also each furnished with a stud or projection f, made preferably in the form of an anti-friction roller, which travels in the grooved cam E or E. The two arms orlimbs f f of the lovers F and F are made adjustable in respect to each other by means of the set screws f for the purpose of adjusting the pressure of the crimping roller F against the can. The two crimping roller carrying levers F and F are exactly alike, except that one is operated by the cam E and the other by the cam E. The cams E and E are also the same excepting that their lower parts e c (which operate to withdraw the crimping rollers from the can to permit the same being inserted over and withdrawn from the can) are located diametrically opposite each other as is clearly indicated by the dotted lines marked 6 and e in Fig. 7. The cams E and E are also of course located on opposite sides of the wheel or carrier G. Two cams are em ployed with their low portions oppositely located so that at each complete revolution of the crimping roller carrier G, the entire perimeter of the can will be operated upon by one or the other of the two crimping rollers; while at the same time both crimping rollers may be simultaneously withdrawn from contact with the seam so as to permit the reciprocating movement of the crimping rollers by which they are brought over the seam and removed therefrom to permit the discharge of the can. two complete revolutions for each can, so that every portion of the perimeter of the can is operated upon twice by one or the other a of the rollers; and nearly the whole perimeter crimping rollers F against the seam with a uniform pressure and to permit the rollers to yield before any unusual obstruction and to accommodate variations in stock. The spring f is mounted between the arms f'if of the levers F and F The intermittently revolving wheel B, which carries the half molds or pockets B, is intermittently revolved or operated from the crank shaft H by means of a crank it thereon, the pin or anti-friction roller h of whichengages radial slots bin the wheel B. The crank shaft H is driven from the driving shaft K by means of the intermeshing gears K and K The reciprocating half mold or pocket 0, 01' its cross head C is reciprocated in its guides C on the frame of the machine by means of the lever 0 connecting link crank C crank shaft 0, crank 0 link 0 and reciprocating bar or cross head 0 which is operated from the main crank shaft by cranks C at each end thereof.

The reciprocating half mold C has a spring cinterposed between it and its cross head 0 to compensate for the oscillating or retreating movement due to the crank motions by which it is operated, and thus hold the half mold G in contact with the half mold B for the required time. By use of this spring connec- In practice, the carrier G is given" tion between the half mold and its cross head we are enabled to employ a crank movement for imparting motion to it.

The cross heads D which carry the dies D are operated from the crank shafts (J by cranks D thereon connected by links D to said cross heads.

The crimping roller carriers or wheels G are driven or revolved continuously by means of gears G thereon which connect with the gears G G the latter being on the driving shaft K or the corresponding shaft K on the opposite side of the wheel. The shaft K takes its motion from the crank shaft [I through the intermeshing gears G G.

As the wheel B revolves it automatically receives the cans from the can delivery device M, the same being preferably a chute or conveyer and discharges them,after the end seams thereof have been rolled, upon the discharge device or conveyer N, the same being preferably a belt or endless carrier operated by a revolving pulley N. p g

The cams E and E it will be understood, correspond in shape or outline to the perimeter of the can to be operated upon.

The machine shown is designed for operation upon ordinary petroleum cans which are square or four-sided, and for this reason the cams E and E are of a somewhat four-sided outline as is clearly shown in Fig. 7.

We claim- 1. The combination with a device B O for automatically delivering the cans into position for operation, of a pair of reciprocating dies, D, adapted to fit within the countersunk heads of the can, rollers or wheelsF operating in conjunction with said dies to roll the seams of the can and mounted upon pivoted levers, revolving carriers or wheels for carrying said levers and seaming rollers around the can,
